Hi. In the neverending series of questions from me, I give you another: Is both the userdb and GenericUserFolder compatible with the original acl_users? I.e, can I develop my site with the basic acl_users functionality, and add one of the two products later on? Or should I start using one of those products right away? I need cookie authentication, but I don't think I understand enough Zope yet to see the big picture, security-wise. And the documentation for GenericUserFolder isn't exactly stunning (not from the newbie spot atleast, no offence :) I would like to concentrate on the main functionality of my site, and add this functionality when my zope zen is a bit better. I'm not doing a horrible mistake thinking that way? Regards, Alexander Limi
